Taylor Swift looked like she was loving life as she celebrated the end of her UK tour with Ellie Goulding and a new haircut.

Known for her trademark long blonde hair almost as much as her ever-changing boyfriends, American pop-country star Swift, 24, showed off a much shorter, wavy hairstyle in a photo selfie posted on her Instagram account.

In the picture, captioned ‘London, I could never thank you enough. See you next time! PS: short hair, don’t care. (!!!),’ the I Knew You Were Trouble singer is also seen hugging her good friend Goulding.

The fellow songstress, 27, turned up as a surprise guest last night for the final date of the European leg of Swift’s RED world tour at the London 02 Arena.

The pair received a deafening response from fans at the sold-out venue as they took to the stage together to duet on Goulding’s hit song Burn.

It’s not the first time that two have performed together, Goulding previously joined Swift at the Staples Centre in Los Angeles when she toured America last summer.
